Calculators have become an indispensable tool for people across various professions, academics and businesses. Calculations are required in almost every field, and a good calculator can greatly simplify the process. However, many people struggle with small screens and cramped buttons on traditional calculators. To address this issue, manufacturers have developed big display calculators that come with larger screens and easy-to-read digits. In this article, we will explore the benefits of big display calculators and why they are becoming increasingly popular.

 Benefits of Big Display Calculators

Improved readability

One of the biggest advantages of big display calculators is that they offer improved readability. Traditional calculators often come with buttons that are close together, making it difficult to distinguish between digits. Moreover, small screens can make it hard to see numbers clearly, especially for people with poor eyesight. Big display calculators, on the other hand, feature oversized digits that are easy to read, even from a distance. This makes them ideal for people who may have trouble seeing small print.

More efficient calculations

Big display calculators can make calculations more efficient by reducing errors. When using a standard calculator, it’s easy to hit the wrong button or misread a number due to small buttons and screens. However, with a big display calculator, users can see their input more clearly and are less likely to make mistakes. Additionally, some big display calculators feature extra-large buttons that are easier to press, reducing the chance of errors further.


Big display calculators are also more convenient than traditional calculators. With a larger screen, users don’t need to strain their eyes when performing calculations. Furthermore, some big display calculators come with features such as built-in memory, which allows users to store previous calculations for later reference. This can be particularly useful for people who need to perform repetitive calculations regularly.

Types of Big Display Calculators

There are several types of big display calculators available on the market today. Here are some of the most common types:

Desktop calculators

Desktop calculators are large, stationary calculators that sit on a desk or table. They usually have a tilted display and oversized buttons, making them easy to use. Desktop calculators are ideal for people who need to perform complex calculations and want a calculator that’s always within reach.

Portable calculators

Portable calculators are designed for people who need to perform calculations on the go. They are small enough to fit in a pocket or purse, but still feature large displays and buttons. Some portable calculators even come with protective covers to prevent damage while being carried around.

Printing calculators

Printing calculators are similar to desktop calculators, but feature a built-in printer that prints out calculations as they are entered. They are commonly used by accountants and bookkeepers who need to keep a record of their calculations.

What are the different types of calculator displays?

There are several types of calculator displays, including LED (light-emitting diode), LCD (liquid crystal display), and VFD (vacuum fluorescent display). LED displays were commonly used in older calculators and feature individual segments that light up to display digits. LCD displays are now more common and use liquid crystals to display numbers and symbols. VFD displays work similarly to LED displays but use a vacuum to generate the light.

What is a calculator screen called?

A calculator screen is commonly referred to as a display or a screen. These terms refer to the area where numbers and symbols are shown when performing calculations on a calculator.

Who made the 1st calculator?

The first calculator was invented by Blaise Pascal in 1642. His machine, known as the Pascaline, was able to perform basic arithmetic functions such as addition and subtraction.

How does an LCD calculator work?

An LCD calculator works by using liquid crystals that change their orientation when exposed to an electric current. The liquid crystals are sandwiched between two pieces of glass and are arranged in segments that form numbers and symbols. When a button is pressed, an electric current is sent through the appropriate segment, causing the liquid crystals to change their orientation and display the corresponding digit or symbol. Unlike LED displays, LCD displays do not require a backlight and use less power, making them more energy-efficient.

What is a big display calculator?

A big display calculator is a type of calculator that features a larger screen and oversized digits, making it easier to read and use.

Who can benefit from using a big display calculator?

Anyone can benefit from using a big display calculator, but they are particularly useful for people with poor eyesight or those who find it difficult to read small print.

What types of big display calculators are available?

There are several types of big display calculators available, including desktop calculators, portable calculators, and printing calculators.

Are big display calculators more expensive than traditional calculators?

Big display calculators may be slightly more expensive than traditional calculators, but the price difference is usually minimal.

Can big display calculators perform advanced calculations?

Yes, big display calculators can perform advanced calculations just like traditional calculators. They simply feature larger screens and more user-friendly design features.

Do big display calculators require batteries or a power source?

Most big display calculators require batteries, but some models may come with a built-in power source or the option to plug into an external power source.

Are big display calculators easy to use?

Big display calculators are designed to be easy to use, with oversized buttons and clear, easy-to-read digits. Some models even feature additional functions and memory storage options to make calculations even more efficient.

How do I choose the right big display calculator for my needs?

When choosing a big display calculator, consider your specific needs, such as whether you require a portable model or a calculator with printing capabilities. You should also consider the size and design of the calculator, as well as any additional features that may be useful for your particular situation.


Big display calculators are a great solution for people who struggle with small screens and cramped buttons on traditional calculators. They offer improved readability, more efficient calculations, and greater convenience. Whether you’re a student, accountant, or just someone who needs to perform calculations regularly, a big display calculator can make your life easier. With a variety of types and styles available, there’s sure to be a big display calculator that meets your needs.
